Abstract

The utility model discloses an SMD transformer which comprises a transformer body and a PCB seat, wherein a plurality of coil windings are arranged in the transformer body, and metal wires are arranged on the coil windings; the PCB seat comprises an upper surface, a lower surface and two side surfaces, and the two side surfaces are both connected with the upper surface and the lower surface; the PCB seat is provided with a plurality of pads; a plurality of positioning through holes which pass through the upper surface and the lower surface are arranged at least one side of the PCB seat, the positioning holes are communicated with the side surfaces and are in one-to-one correspondence with the pads; and the metal wires are welded and connected with the pads. When being welded on the pads, the metal wires can be positioned through the positioning through holes, thus not only being convenient for welding the metal wires on the pads, but also leading to small volume, and enabling the SMD transformer to be welded on the PCB easily.
本实用新型公开了一种SMD变压器,其包括一变压器本体及一PCB板座,所述变压器本体内设置有若干线圈绕组,所述线圈绕组设置有金属绕线。所述PCB板座设置有一上表面、一下表面及两侧面,所述两侧面均与所述上表面及下表面相连,所述PCB板座设置有若干焊盘。所述PCB板座至少一侧开设有若干贯穿所述上表面及下表面的定位通孔,所述定位通孔与所述侧面相连通并与所述焊盘一一对应,所述金属绕线与所述焊盘焊接相连。本实用新型在将所述金属绕线焊接到所述焊盘上时,可通过所述定位通孔对所述金属绕线进行定位,从而不仅便于将所述金属绕线焊接到所述焊盘上,而且体积小及易于将本实用新型焊接到电路板上。
